fairfax. definitely the coldest night of the season and again the frost advisories expand a bit now to include the district and prince george's county, freeze warnings in effect north and west of town. so tomorrow morning sunny with a cold or frosty start. if you folks in southern maryland, charles county and st. mary's county, don't have to worry about anything tonight, chilly start 30s and 40s, winds easterly at 10. by afternoon great, mostly sunny, cool but nice. you need sunglasses, high temperatures between 60 and 65 and winds not a factor southeasterly at 10. only 42 in oakland tomorrow, autumn glory festival goes through sunday, 50 in cumberland, looking at mid-50s for hagerstown, martinsburg, maybe 59 in winchester. the winner on this map is culpeper, 64, but warrenton, manassas, leesburg, fairfax, 60, 61, downtown 62. get into charles county past la plata, waldorf, probably get to the mid-60s, 64 for annapolis.
